The Logic Handbook is a clear and concise introduction to logic for aspiring philosophy students. It provides a complete introductory course and carefully guides the reader through the topics of logic that are most important for the study of philosophy. It covers propositional and predicate logic, with and without identity. Additionally, it includes a presentation of the semantics of these languages, including definitions of truth and satisfaction. Natural deduction is used as the proof system. Volker Halbach introduces the essential concepts through examples and informal explanations, as well as through abstract definitions. The Logic Handbook offers the best entry point into the general abstract thinking about language, logic, and semantics that is characteristic of contemporary philosophy. Exercises, examples, and sample exams are available on a companion website.
